我的VirtualMachine上的buildroot网络有问题。当我输入ifconfig我得到答案:
eth0:获取接口信息时出错:找不到设备
在控制台上加载buildroot时,我看到:
ip:找不到设备eth0
ip:SI0CGIFFALGS:没有这样的设备
我找不到解决这个问题的方法。
答案 0 :(得分:4)
# make linux-menuconfig
Device drivers —>
Network device support —>
Ethernet driver support—>
选择
<*> Intel(R) PRO/100+ support
<*> Intel(R) PRO/1000 Gigabit Ethernet support
<*> Intel(R) PRO/1000 PCI-Express Gigabit Ethernet support
<*> Intel(R) 82575/82576 PCI-Express Gigabit Ethernet support
[*] Intel(R) PCI-Express Gigabit adapters HWMON support
<*> Intel(R) 82576 Virtual Function Ethernet support
现在应该使用VM。

您的问题不是Buildroot问题,而是内核配置问题。
答案 2 :(得分:0)
关于如何找到VM真正需要的NIC驱动程序的更有用的解释。
首先,使用lspci查找NIC的关键字。
lspci | grep -i ethernet
00:03.0以太网控制器:英特尔公司 82540EM 千兆位 以太网控制器(rev 03)
然后,在内核驱动程序源代码目录中grep关键字:
grep -nr'82540EM'driver / net / ethernet /
的驱动/净/以太网/英特尔/ E1000 / e1000_hw.h:417:#定义 E1000_DEV_ID_82540EM 0x100E drivers / net中/以太网/英特尔/ E1000 / e1000_hw.h:418:#定义 E1000_DEV_ID_82540EM_LOM 0x1015 drivers / net / ethernet / intel / e1000 / e1000_main.c:780:case E1000_DEV_ID_82540EM: drivers / net / ethernet / intel / e1000 / e1000_main.c:781:case E1000_DEV_ID_82540EM_LOM: drivers / net / ethernet / intel / e1000 / e1000_hw.c:276:case E1000_DEV_ID_82540EM: drivers / net / ethernet / intel / e1000 / e1000_hw.c:277:case E1000_DEV_ID_82540EM_LOM:
最后,找到NIC的内核配置: 在相同的目录路径下打开相应的Makefile。
vim drivers / net / ethernet / intel / e1000 / Makefile 你会发现:
obj - $( CONFIG_E1000 )+ = e1000.o
e1000-objs:= e1000_main.o e1000_hw.o e1000_ethtool.o e1000_param.o
结论: CONFIG_E1000是您的NIC需要的。

在启动日志的最后一行,您可以添加Intel(R) PRO/1000 PCI-Express Gigabit Ethernet support
